This cache is out on the spit and I recommend going along the spit not cutting out to it. If you head down the main path from the car park turn right straight after going through the first gate. You will quickly come to a second gate. Once you have gone through this one there are many tracks that lead down onto the beach and you will be fine from there.
One you get to GZ im sure you will find it. Please be careful when extracting the cache and place back well. This is an area where birds nest so please be very respectful of the nearby wildlife. BYOP
At the time of placing there was a trackable and plenty of room for swag.
